    Customer Testimonials
    Lauren Mack

    "At first I did not think I was going to receive any help. I was redirected to the Mfg and they gave me the information I needed. I am glad the sales rep had me talk to the Mfg, this way the sales rep and the firm received my business because they did not lie to me just to receive the sale. After looking at many web sites, I went back to Clary because of the help I received and the up front salesmanship of the staff. "


    "I attempted to order this particular product from several online vendors, and was sadly disappointed with the poor service of these companies, as well as their abysmal turn around wait. However, I turned to Clary business machines because of high customer reviews. Placing my order,I heard from Clary within the hour, with several follow up emails. On top of that, my order shipped within 4 days! When I attempted to order the same product from certain mainstream electronics vendors, I had waited over a month for word on my order to be shipped, to my disappointment. Eventually, I canceled the order and had nearly given up hope on finding my product. Thanks to CBM, I will have my product sooner then I had ever hoped."
